To wllnwham it may concern:

Be it known that I, JOSEPH E. CAMP, a citizen of theUnited States,residin at Washington, in the county of Tazewel and State of Illinois,have `invented certain new arid useful Improvements 'inl Dumps; and I doherebydeclare that the following is a full, clear, and exact description'side elevation of the dump Wit of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to 'improvements in portable grain-dumpa` j Theobject of the invention is toprovide a light, inexpensive, but efficientgrain-dum of the portable kind which will be under pe ect control whilein use.

In the appended drawings, Fi e 1 is a shown thereon.. Fig. 2 is a planview of the Fi 3 is a sectional elevation of the wagonwheel restingthereon and a frame in contact with the wheel and used to raise thefront end ofthe wagon. Fig. 4 is a View of la gearingused with the dum,part being shown in section. Fig. 5 is a face view of aninternally-toothed gpm-wheel, showing other gears used therewit f "'Theplatform of the dump is indicated by the letter A, lthe same beingrovided near one end withwheels B, the ot er end with a tongue C, towhich horses may be hitched for transportation purposes. Erected uponthe platform at each edge is a de rrick-frame D, on the forward limb ofeach of which a frame E, carrying rollers F, is designed .to travel.

Said frames E are attached to a Wagomraising frame G, normally seated inthe latform A,'lush'with the u per surface of t e same. Atthe top ofeach errick-frame is a grooved pulley H, over which runs a cable I, oneend of which is attached to the frame E, the other A end havingconnection with 'a drum J on a shaft K, having bearings in the sills ofthe platform, in anygood manner, but Vnot shown.v One endof the 'shaft Kis provided with a worm-wheel L, with which engages a Worm M, carried ona two-piece shaft composed of two abuttin portions N and N', journaledat one side of t e platform at right angles to the shaft K The partshaft N is driven from the'power (not shown) by means of a bolt Ol andpulley P. Secured to the part shaft N is an internallyetoothd drumS--for instance u by a key T, as shown.. The end of the Portable GrainaWagon other shaft portion N terminates within the hub of the drum Sadjacent to the end ofthe shaft N, a's clearly shown in Fi 4. This endof said shaft- Nis provided wit a pinion-gear U, aflixed thereto in anysuitable 1nanner-- for instance, as by a key-and adjacent to said inionand loose on the shaft is an varm V, w` ose extremity carries a gear W,enga ing the teeth of the drum S and the pinion L. A jacent also to thearm is a loose sleeve Y, adapted to shift yalong the shaft, for thepurposes to be hereinafter described. Pivoted i on a yoke R, secured tothe platform A, is an arm X, whose lower end is connected to thesaidshifting sleeve Y b -a link Z. The upper end of the arm X as looseconnection with a hand-lever 2, pivoted on said yoke R or to any otherpart of the machine desired. Said arm X also pivotally connects with apushrod 3, guided in a raised portion 4 of the yoke, as shown in Fig. 5.A fork 6 is loosely carried by the sleeve Y and has an arm 7 at rightangles to its length parallel to the shaft' N, as shown. Said varmpasses through and is held by the arm V, as will be understoodpresently.

In operation the shaft N is driven toward l the observer, asindicated bythe dart on the belt O, and whenJ the dump is at rest the pinionU mustalso revolve continually, therey transmittingl motion to the gear Thelatter, being ins mesh with the gear-drum S, will travel'within saiddrum without moving l the shaft N, since less force is used -in turningthe arm V' about the shaft N than raising the dumping-frame' G. If now awagon to be unloaded is placed Au on the platform with its frontwheelson the ame G and the handlever 2 is moved to the right as viewedin the drawings, the result is to push the pin or rod 3 into thepath ofsaid revolving arm V, as shown by dotted lines in Fig. 4. As the armmakes its circuit it meets the said pin 3 and stops. Since the yarm isbrought to a stop and the gearWmust still revolve, due to pinion U,while still in mesh with the gear-drum S, said drum is thenmade torevolve in a direction opposite to that of the gear W and impartingrevolution to the Worm, and consequently the lworm-wheel L. The shaft Kis thus revolved jto turn the drums jJ and take up the cables I. In sodoin the frame G rises out'of its seat in the atform, as shown in Fig.3, and meets the w eel lodging between the. members thereof, so that theence to the conveyer or drag 8, located be, hind it. When the wagon israised to the desired height, it isstopped by throwing the lever 2 backto its initial position, thereby withdrawing the pin 3 and releasingthenrm V, which is again free to revolve as before, the wagon remainingin the raised position.

The movement ofthe lever 2 may be shifted either automatically or byhand, as desired. Erected on the platform is an upright 9, havingarock-arm 11 thereon, one end of which is designed vto be met bythe frameG in its upward movement, the yother end having connection with thehand-lever 2 through a d rod 10, as shown in Fig. 1.

Evidently as theI said member G rises it will strike the arm 11, and therod 10 will be drawn to move the pin 3 in `an opposite directiontorelease the said arm-V; as described. "When desired to retu-rnthe'wagon to itsnormal position, they lever 2 is moved still farthertoward the left, with the result that the pin 7V of the fork 6- isentered between the teeth of the pinion U and gear W, thereby'stoppingthe revolution frame G. When .the-latter-memberv has reached itsposition -of rest, the lever 2 may be moved to Withdraw the pin' 7, orthis may be ydone automatically by rovio ing a short rock-shaft 12 underthe p atform, one enfi` having an arm 13, with which the frame Gcontacts when lowered, the other end having an upwardly-extending arm1.4, connected by a pu l-rod -15 to Yan'extension of the lever 2 be 0Witsp'ivot Saidrod 15 is-slotted at-its endj'so that the lever maybemoved byhand i tempted toi S'o without being lhindered by said rod whenagain-throwing the mechanism in position to again raiseV the frame G.
